Dumb question but i am getting ready to order a Lunar water temp guage (and trans, and fuel pressure) and i have the JDM elect fan kit with the water temp sensor installed. Do you just connect the guage sensor wire up to the existing fan kit sensor? What did you do?

 

I decided to tap into the "Return" line for the intercooler to get a reading as the "cooler" fluid goes back in.

 

Thanks lil Ricky. I'm having a hard time visualizing how you tapped into it this way? Didn't do use a sensor?
